19 year old male looking for roomates to share rent with

I would like a couple other like-minded people to share an apartment with. I will be taking a certificate program for a month and then start teaching in English in Madrid! Would prefer if you had an interest in teaching English as well but can also be studying at uni.

I saw a lot of the like 7-10 room apartments, I thought I would try and see if I could find a couple of others that I could split rent with instead of spending 300 euros on a tiny room.
